Stoke have rejected a second offer of £20million from West Ham and want closer to £30million for Arnautovic.

They feel the Austrian forward is worth that amount because he has three years left on the contract he signed last summer.

Arnautovic, 28, is trying to force a move from Stoke by slapping in a transfer request, but the Potters are adamant he will only leave on their terms.

Stoke are also taking a tough line over Giannelli Imbula and insist their record £18.3million signing will not be leaving on loan.

Boss Mark Hughes is open to offers for the French flop and the Potters have rebuffed loan inquiries from Nice and Galatasaray.

“We’ve invested a lot of money in G,” said Hughes. “If a club comes and a bid is on the table that we think makes sense to us, then we would consider it. But at the moment no-one has come up with anything that is attractive to us.

“It’s more loans, which really we’re not interested in to be perfectly honest.”
